Illustrative example

RO Read-only. We never connect to your brokerage — alerts only.
$0 No card to start. Build a watchlist and set alerts on the free tier.
Email only. No app to keep open, no dashboard to babysit. Cooldowns prevent spam.

Built to be quiet and exact.

Alerts you can trust to fire once, on time, and never spam you.

Cooldowns, not noise

One alert per trigger, then a cooldown. A stock hovering at your target won't flood your inbox — you get the signal, not 50 emails.

ET

Market-hours & date aware

Prices checked against US market hours, timestamps in ET. Earnings and ex-dividend alerts fire a few days ahead — never after the cut-off.
